we took Relative difference as Pingminrtt-httpminrtt/(0.5* (Pingminrtt+httpminrtt)). it helps in finding how big the difference is in ,we can expect from ping RTT relative to HTTP RTT
The x-axis shows the ranges of realtive differences interval between min and max of relative differenceof relative differences .Left Yaxis is the number of times the difference exist in between the rangesshows how many times a particular difference value exists .The right Yaxis is cumulative %age which shows what percentage out of the total,a particular interval value is occurring.
Differences are quite small as we can see from x-axis bin intervals. More over, most ping and HTTP min RTT of almost all of the nodes are having 0 difference between ping minRTT and HTTP minRTT which confirms that there is no such significant difference occurs if we use ping or HTTP.insignificant difference which confirms that if we ping a node using ping utility or HTTP, it would not be much of a difference.
70%-94% of times, 70% to 94% of times the relative difference lies between 0-0.04 which reflects that ping RTT and HTTP RTT doesnot show much of the differenceis again a very small value.
